The Ultrafine-Grained Titanium and Biomedical Titanium Alloys Processed by Severe Plastic Deformation (SPD)
the function of our tissues and organs. Among the biomedical materials, titanium alloys have received attractions for dental and orthopedic implants due to their high strength, great corrosion resistance and biocompatibility, and low density [1,2]. Recently, a series of new β titanium alloys have been developed with low elastic modulus, containing non-toxic alloying elements such as Nb, Ta, Zr ...
متن کاملAn Ebsd Investigation of Ultrafine-grain Titanium for Biomedical Applications (postprint)
High-resolution electron backscatter diffraction (EBSD) was used to examine the grain structure in long rods of ultrafine-grain (UFG) commercial-purity titanium produced for medical implants. The UFG material was obtained by equal channel angular pressing (ECAP) using a Conform scheme followed by rod drawing. The microstructure was found to be bimodal consisting of relatively coarse elongated g...
متن کاملMechanical Behavior of an Ultrafine/Nano Grained Magnesium Alloy
The application of magnesium alloys is greatly limited because of their relatively low strength and ductility. An effective way to improve the mechanical properties of magnesium alloy is to refine the grains. As the race for better materials performance is never ending, attempts to develop viable techniques for microstructure refinement continue. Further refining of grain size requires, however...
متن کاملTitanium nanostructures for biomedical applications.
Titanium and titanium alloys exhibit a unique combination of strength and biocompatibility, which enables their use in medical applications and accounts for their extensive use as implant materials in the last 50 years. Currently, a large amount of research is being carried out in order to determine the optimal surface topography for use in bioapplications, and thus the emphasis is on nanotechn...
متن کاملMechanical Strength and Biocompatibility of Ultrafine-Grained Commercial Purity Titanium
The effect of grain refinement of commercial purity titanium by equal channel angular pressing (ECAP) on its mechanical performance and bone tissue regeneration is reported. In vivo studies conducted on New Zealand white rabbits did not show an enhancement of biocompatibility of ECAP-modified titanium found earlier by in vitro testing. However, the observed combination of outstanding mechanical...
